Examples

Acceleration is typically read in the reading event callback. In the example below this occurs sixty times a second.

js
const accelerometer = new Accelerometer({ frequency: 60 });

accelerometer.addEventListener("reading", (e) => {
  console.log(`Acceleration along the X-axis ${accelerometer.x}`);
  console.log(`Acceleration along the Y-axis ${accelerometer.y}`);
  console.log(`Acceleration along the Z-axis ${accelerometer.z}`);
});
accelerometer.start();
